The invention discloses a distributed battery power supply system and a power supply method. The distributed battery power supply system comprises a whole vehicle management system and at least one sub power supply system. When a charging and discharging module in the sub power supply system breaks down, the whole vehicle management system controls the charging and discharging module to disconnectfrom the corresponding battery module and the corresponding electric load and controls the battery module to supply power to the corresponding electric load; the whole vehicle management system is further used for controlling the battery module to be disconnected with the corresponding charging and discharging module and the corresponding electric load when the battery module in the sub power supply system breaks down, and controlling the charging and discharging module to supply power to the corresponding electric load. According to the scheme provided by the invention, when a single-point fault occurs in the power supply system, the connection between the battery outside the fault point and the fault point is cut off, so that the influence caused by the single-point fault is reduced, and the safety of the power supply system is improved.

    本发明公开了一种分布式电池供电系统及供电方法,包括整车管理系统,至少一个子供电系统,整车管理系统在子供电系统中的充放电模块出现故障时,控制该充放电模块断开与对应电池模块、以及对应用电负载之间的连接,并控制该电池模块为对应用电负载供电,整车管理系统还用于在子供电系统中电池模块出现故障时,控制该电池模块断开与对应充放电模块、以及对应用电负载之间的连接,并控制该充放电模块为对应用电负载进行供电。本发明提供的方案在供电系统出现单点故障时,采取切除故障点外电池和该故障点的连接,降低了单点故障带来的影响,提高了供电系统的安全性。
